SUJET : Enforcing heterogenous responses

I'd like to use LimeSurvey as a part of a course peer assessment exercise. Basically, my students are working together in groups and part of their grade is determined by their peers' evaluation of their contribution. This part of a Team Based Learning teaching approach (e.g. see Michaelsen, Knight, and Fink's Team Based Learning (2004)).

The idea is that students will have Y other team members and have Y x 10 points to allocate in four different categories (preparation, contribution, respect for others, and flexibility to others ideas and suggestions). Most of the times students sense of 'fairness' will cause them to give everyone 10 points, regardless of the variation in student contribution. As a result, I want to enforce some heterogeneity. That is, force the students to give at least one student <= 9 points and another student >=11 points.

I'm familiar with LimeSurvey, but have no idea how to implement such a protocol. Does anyone out there know?

Thanks for your help with this.

I'm a very basic user so here's my very basic survey. A few notes, I tried using array numbers for the peerScores part but it gave me a drop down menu that only ranged from 1-10. I need 1-15 so I went with array texts question structure.

2) Add the following script to the source of the array. This script:
- Automatically identifies the parent question
- Inserts a "Points available" row
- Only allows entries between 1 and 15
- Does not allow entries exceeding the category total (10 x # of peers))
- Validates each category (column) to ensure that all inputs have a value and there is at least one entry under 10 points and at least one entry over 10 points

Thanks for your help with this. It's very close to exactly what I need.

Unfortunately, I'm not familiar enough with JavaScript and LimeSurvey to figure out how to make it exactly what I need. So if you are feeling charitable and want to modify the code so that the 'Points Available' is 10 x the number of first names entered, I would be be very grateful (i.e. make a donation to limesurvey!)

I agree. I've implemented the 'dumb' version for now. If you're interested in helping us with this for next time I teach, I would be grateful (but I am not expecting this). Otherwise, I'll look around to see if I can find someone at my institution who can help with this in the future.
